From 66395927e5a853898824a2aa9eeb0a1a24e70d5f Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Thu, 12 May 2022 08:30:21 +0300 Subject: [PATCH] bus: ti-sysc: Fix warnings for unbind for serial We can get "failed to disable" clock_unprepare warnings on unbind at least for the serial console device if the unbind is done before the device has been idled. As some devices are using deferred idle, we must check the status for pending idle work to idle the device.
